My understanding was that is an ACR (Adobe Camera Raw) issue. ACR to my info ACR is used by all Adobe products (Photoshop, Lightroom, Photoshop elements) for raw conversion.

I have neither of the cameras in question and am presently not using Adobe raw converters (used them in the past) - so I have no clue whether the issue with the E-620 and E-30 got ever fixed.

I understand from discussions I followed on other web-sites that Capture One is one of or the best regarding sharpness. Some time ago I had a Capture One license and it was amasing what detail this pulled from E-300 files. Since moving into the Mac environment I am using Aperture. Mostly for its colours.

No doubt that there used to be problems with Adobe Camera RAW /Lightroom and some Olympus RAW camera formats - the E-400 for example. often resulted in what looked like micro fractures in the fine detail of an image.

But we're now on the 7th generation of Adobe Camera RAW. I haven't noticed any problems with Adobe's RAW conversions for a long time.

On the plus side, the E-450 has the same improved TruePic III+ image processor as the E-30 and E-620 that solved the problem of high ISO dark area banding in the E520/420 and earlier. DxOMark measurements show it has about half an EV greater dynamic range than the E-510.

On the other hand the E-450 has no in-body image stabilisation. Although an E-450 is likely to be cheaper second hand, the bargain model in my view is the E-620 - not much larger, 12MP (but basically the same ISO noise and dynamic range), IS, articulating screen, bigger viewfinder and 7 AF points instead of 3, and these AF points work to 1EV less light.

I knew some body who said they had removed or disconnected the AA filter on a 510, but I have no idea how that would be done if at all true. I think it would involve some in depth knowledge of the inner workings of the camera.
